Abstract
Official abstract text for this publication.
Provided are a vibrating body for speaker device which prevents interlayer from peeling in advance and includes a large effective vibration area, and a speaker device including this vibrating body for speaker device. The vibrating body for speaker device includes a first interlaced fiber member, and a second interlaced fiber member which overlaps with the first interlaced fiber member, and one of the first interlaced fiber member and the second interlaced fiber member includes polyvinyl alcohol fibers containing boron, and an outer circumferential portion of the first interlaced fiber member is larger than an outer circumferential portion of the second interlaced fiber member.
First claim
Opening claim text (preview).
The invention claimed is: 1. A vibrating body for speaker device comprising: a first interlaced fiber member; and a second interlaced fiber member overlapping with the first interlaced fiber member, wherein one of the first interlaced fiber member and the second interlaced fiber member includes a polyvinyl alcohol fiber containing boron, wherein the first interlaced fiber member includes a bent portion and a first vibration portion, wherein the second interlaced fiber member includes a second vibration portion, and wherein fibers of the first interlaced fiber member are longer than fibers of the second interlaced fiber member. 2. The vibrating body for speaker device according to claim 1 , wherein an inner circumferential portion of the first interlaced fiber member and an outer circumferential portion of the second interlaced fiber member are connected. 3. The vibrating body for speaker device according to claim 2 , wherein the first interlaced fiber member includes an annular shape. 4. The vibrating body for speaker device according to claim 1 , wherein the polyvinyl alcohol fiber of the first interlaced fiber member including boron are longer than the polyvinyl alcohol fiber of the second interlaced fiber member including boron. 5. The vibrating body for speaker device according to claim 4 , wherein the bent portion is arranged between an outer circumferential portion of the first interlaced fiber member and an outer circumferential portion of the second interlaced fiber member. 6. The vibrating body for speaker device according to claim 1 , wherein a water melting temperature of the polyvinyl alcohol fiber including boron is higher than 80° C. 7. The vibrating body for speaker device according to claim 2 , wherein a water melting temperature of the polyvinyl alcohol fiber including boron is higher than 80° C. 8. The vibrating body for speaker device according to claim 1 , wherein the polyvinyl alcohol fiber is a crimped fiber. 9. The vibrating body for speaker device according to claim 2 , wherein the polyvinyl alcohol fiber is a crimped fiber. 10. The vibrating body for speaker device according to claim 1 , wherein a cross-sectional shape of the polyvinyl alcohol fiber is formed in a circular or in an elliptic shape. 11. The vibrating body for speaker device according to claim 2 , wherein a cross-sectional shape of the polyvinyl alcohol fiber is formed in a circular or in an elliptic shape. 12. A speaker device comprising the vibrating body for speaker device according to claim 1 . 13. An electronic device comprising the speaker device according to claim 12 . 14. The vibrating body for speaker device according to claim 1 , wherein the first interlaced fiber member and the second interlaced fiber member includes a polyvinyl alcohol fiber containing boron.
